COATING DEVICE.

Specification of Letters Patent.

Patented Jan. 6, 1920,

Application filed August 21, 1919. Serial No. 318,871.

To all whom it may concern I Be it known that I. FRANK H. Snenrno, J11. a citizen of the United StMZGS I'QSIClHIg at Salem, in the county of Columbiana and State of Ohio. have invented a new and useful Coating Device, of which the followlng is a specification. I

The invention relates to coating devices and has more especial reference to a device of this character designed to coat chlna or porcelain plates and similarly shaped. articles with the liquid coating of glaze which 1s ordinarily applied to such articles.

The objects of the invention are to provide a device which automatically coats the plates or other articles, removes the excess liquid coating therefrom. and delivers the coated articles from the machine.

Further objects are to provide a devlce of this general character comprising a tank containing the liquid coating, an oppositely inclined track leading through the trough, a drum within which the articles to be coated are placed and means for moving said drum over said-track and delivering it from the tank.

. With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter descr bed, illustrated in the accompanying drawings, and particularly pointed out 1n t e appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made within thescope of the appended claims, without departing from the spirit or seenficing any of the advantages of the invention.

The invention thus set forth in general terms is illustrated in the, accompanying drawings forming part hereof, 1n wh1ch- Figure 1 is a longitudinal sectional view of the device;

Fig: 2, a plan View of the same;

Fig. 3, a section taken on the line 3 3, Fig. 1; and Fig. 4, a detail perspective view of the drum. I I

A practical embodiment ofthe invention is disclosed in the accompanying drawings, forming apart of this specification in which similar numerals of reference indicate corresponding parts throughout the several views.

The tank 1 may be of any usual construction and contains the coating in a liquid form. A pair of spaced rails 2 are located through the tank and extend downwardly as shown at 3 from the feed end of the tank to the longitudinal center of the tank as shown at 1 and then upwardly at a steeper incline as shown at 5 to a point 6 above the farther end of the tank, the delivery ends of the rails terminating in downwardly inclined portions 7.

A toothed track 8, of the same shape as the rails 2 is connected upon the inner side of each rail. As will be hereinafter described the drums which contain the plates or other articles to be coated are provided with toothed wheels which ride upon the tracks 8, the axles of the drum riding upon the rails 2.

Each drum comprises the circular heads 9, each provided with a concentric outwardly protruding axle 10 arranged to ride upon the rails 2, a toothed wheel 11 being mounted upon the outer end of each axle and ar ranged to engage the toothed tracks 8.

The heads 9 are connected together by the spaced cross bars 12 each of the cross'bars being provided with spaced lugs 13 upon its inner face forming a rack within to receive the plates as shown at A in Figs. 2 and 3.

One of these cross bars designated by the numeral 14 is hinged at one end to one of the heads 9 as shown at 15, the other end being provided with a suitable catch 16 by means of which it is detachably secured to the other head. By this construction the catch 16 may be released and the bar 1d swung outwardly upon its hinge to permit plates or the like being placed within the drum or removed therefrom.

' The rear or delivery ends of the rails 2 and tracks 8 are supported by the uprights 17 which extend upwardly from the rear end of the tank 1. An upper rail 18 is spaced above and parallel with the upwardly extending portion 5 of each of the rails 2,

said upper rails being supported at their rear extremities by the side walls of the tank and at their upper extremities by the uprights 17. Each of these upper rails is curved at its lower end as shown at 19 and at its upper end as shown at 20 and they are spaced a suflicient distance from the portions 5 of the lower rails to form a guide slot 21, through which the axles 10 of the drum extend.

Bearings 22 are mounted near the upper ends of the rails 18 on the upper sides thereof and a shaft 23is journaled in said bearings, a crank 2% or other suitable means for rotating said shaft being provided thereon. A pair of spaced sprocket wheels 25 are fixed upon the shaft 23 at points slightly spaced from the inner faces of the, rails.

A shaft 26 is j ournaled in suitable bearings 27 located near the lower extremities of the rails 18 and a pair of spaced sprockets 28 similar to the sprockets 25 and alined there? with are fixed upon the shaft 26. An endless chain 29 is located around each alined pair of sprockets and '28. each of said chains being provided at intervals with hooks 20 as best shown in Fig. 1 of the drawings.

The operation of the device is as follows: The hinged cross bar l-t is swung outwardly from the drum as above described and the plates A or other articles to be coated are placed within the drum after which the hinged arm is moved back into the closed position and the catch 16 fastened.

The drum is then placed at the upper or feed end of the portions 3 of the rails 2, the toothed wheels 11 thereon engaging the teeth upon the track 8. The drum will then he carried by gravity down the inclined portions 3 of the rails and tracks into the tank, immersing the plates therein in the liquid coating. The endless chains 29 will be rotated in the direction of the arrow in Fig. 1 and as the drum reaches the point 4- upon the rails the hooks 30 will engage the axles 10 of the drum, carrying it up the inclined portions 5 of the rails, the toothed wheels 11 upon the drum by their engage ment with the toothed track causing the drum to rotate forwardly as it moves upwardly out of the tank. This rotation of the'drum through the tank and upon the track leading from the tank will cause the liquid coating to be spread evenly over the entire surface of each plate and will cause any surplus liquid coating upon the plates As to be removed by centrifugal action. the drum reaches the upper end of the inclined portions 5 of the rails it will be guided on to the downwardly inclined portions 7 of the rails by the curved portions 20 of the guide slot, the drum rolling down these inclined delivery ends of the rails from which it is removed and opened and the.

coated plates removed therefrom, and again placed in a kiln in the usual manner to burn the glaze upon the plates.

With this construction of coating device a large number of plates may be quickly and properly coated in a short time as the drums may be quickly filled and passed through the device with a minimum of labor.

It will be understood that although the device is described as being especially dedesigned for use in coating china and porcelain ware with a'glazed coating, that it is adaptable to use for various forms of coattank containing liquid, toothed tracks ex-' tending through said tank, a drum containing articles to be coated, toothed wheels upon said drum arranged to engage the toothed tracks and means for passing the drum over said tracks.

A liquid coating device, including a tank containing liquid, rails extendin clownwardly into the tank and upwardly out of the tank, a drum containing articles to be coated and arranged to be moved downwardly upon said inclined rails into the tank 1 and means for carrying the drum up the inclined rails out of the tank.

A liquid coating device, including a tank containing liquid, rails extending downwardly into the tankand upwardly out of the tank, a drum containing articles to be coated and arranged to be moved downwardly upon said inclined rails into the tank, means for carrying the drum up the inclined rails out of the tank, and means for rotating the drum upon said rails.

6. A liquid coating device, including a tank containing liquid, "toothed tracks inclined downwardly into the tank upon one side and upwardly out of the tank on the opposite side, a drum containing the articles to be coated, toothed wheels upon said drum for engaging the toothed tracks, said drum arranged to be rolled down said inclined tracks into the tank and means for moving the drum up the inclined tracks out of the tank. Y

7.
